Image is missing, so i have attached it.
Answer:
Rate of change = 2
Step-by-step explanation:
From the image attached, we are given a parabola which opens upwards with many points marked on the curve.
We are asked to find the rate of change for the interval between 3 and 6 on the x axis.
Now, rate of change of any function f(x) from a to b is given by the formula ;
Rate of change = [f(b) - f(a)]/(b - a)
For this question, a = 3 and b = 6
f(3) is simply the y-value when x is 3. On the graph, f(3) = -2
Similarly,f(6) = 4
Thus;
Rate of change = [4 - (-2)]/(6 - 3)
Rate of change = 6/3
Rate of change = 2
Answer:
about 30 ft
Step-by-step explanation:
Statements A, B, C, D are (approximately) correct.
Using the observations in A and B, Carl's horse travels farther by ...
90 ft - 60 ft = 30 ft . . . in one complete turn
Solution:
Albert's medical expenses is = $ 12,000
Sam's come = $ 8,000
Add the amount = 12000 + 8000 = $ 20000
Sue Jones is insured for the amount = 10/20
Now, find the insurance.
(10/20)*(20,000) = 10000
Hence, $10000 pay for the insurance.
The missing number is the square-root of the constant term on the left-hand-side, which equals sqrt(1/16)=1/sqrt(16)=1/4.
Check:
(x+1/4)^2=x^2+2*(1/4)x+(1/4)^2=x^2+x/2+1/16. ok
Answer: x= 1/4
Since the range of the scores given was between 300 and 700 (which is 2 standard deviations below and above the mean), the probability that a randomly selected student's math score - as based on the empirical rule of statistics - is 95%. In decimal form, it is .95.
